Is "infinitive" form the same thing as "informal low form" or "informal spoken form" ? I have been learning verb conjugation and keep running into different descriptions of the various forms. I've created my own cross reference noting that, for example, "polite spoken form", "informal high respect", and "polite" are all the same depending on which Korean language website you read. One thing I can't figure out is whether "infinitive" is the same thing as "informal low form" and "informal spoken form." It seems to be the same spelling but I can't find any good explanations that say exactly that. Example: 먹다 From verbix.com korean conjugator I get this declarative present informal low 먹어 meog-eo That's the same as the infinitive form spelling 먹어 as described at http://hanguladay.com/tag/infinitive-form/ Can someone confirm this?
